Many thanks to all of you guys !
I'm going to test the different methods...

Marc >>> I also made this model to explore the Gordon tool...it is still difficult to me...You get exactly the thing...

Efra >>> You mean offset tool with the main outilne curve divided in two ?

Fitz >>> The net surface ?? As I use french version, I'm not sure what tool it is.

Anyway, thanks again.
